The course provides: The basic elements for the definition of the nutritionally adequate diet for
the different population subgroups;
The description of major methods designed to measure food and/or
nutrient intakes in population groups.
Moreover, a special attention will be paid on the description of nutrient
and non-nutrient composition of the main foods usually consumed in the
